Spanish AI writing detection model update

We're releasing an update to our AI writing detection model for Spanish submissions that improves detection of AI-generated content from newer large language models (LLMs), including GPT-5, GPT-5-mini, GPT-5-nano, GPT-5.1, Gemini-2.5-pro, Gemini 2.5 Flash, and tools based on these LLMs, while maintaining our low false positive rate.

This release only affects Spanish submissions.

This update does not introduce any visual changes to the AI writing report or changes to product functionality beyond the improved detection. If you currently license Turnitin Originality or iThenticate 2.0 and have AI writing detection enabled on your account, the updated model applies automatically — no action is required.

Note: This update does not retroactively update previously generated AI writing reports. To view scores generated by the updated model, existing submissions must be resubmitted.

What to expect

• Why is Turnitin updating the model? 
  Given the rapid evolution of large language models, it is our goal to regularly update our AI writing detection model in an effort to keep pace with the latest generative AI tools. This update enhances detection of content generated by newer LLMs like GPT-5, GPT-5.1, Gemini-2.5-pro, and Gemini 2.5 Flash while maintaining our <1% false positive rate for documents with over 20% of AI-written text.
• Will this change my AI detection scores & why?
  Previously generated AI writing reports are not affected by this update unless those papers are resubmitted after the update goes live. In that case, there may be a change in score as the AI writing detector will evaluate the papers based on the updated model and its capability to detect content from newer LLMs. With improved detection, this may result in higher AI scores on new submissions, but with every update, we prioritize not incorrectly flagging human-written text.
• Will existing submissions be checked retroactively?
  No. This update applies only to new submissions. If you'd like to see a score generated by the updated model, you'll need to resubmit the document.
• Does this change my workflows?
  No. This update does not introduce any changes to how the product looks or functionality beyond improved detection. There are no visual changes to the AI writing report, and no changes to your settings or configurations are required.

Read-Only User Permissions

Administrators can now assign a read-only permission to users in iThenticate, allowing them to view similarity reports and access submission results without the ability to upload submissions. This gives institutions greater control over who can submit content and how submission volume is managed.

This release will help you:

• Control submission access at scale by assigning read-only permissions to users who need visibility into similarity reports but should not be uploading content
• Manage submission volume and enforce institutional policies by restricting upload access to authorized users, reducing the risk of unintended submissions counting against licensed limits
• Involve more stakeholders in the review process — such as reviewers, editors, and compliance officers — without increasing submission volume or licensing risk

How can you get access to this feature?

This feature will be automatically available to all iThenticate customers. No action is required to enable the functionality.

To assign read-only permissions, Administrators can navigate to the Users menu and configure permissions for the desired user. Users assigned read-only permissions will retain full access to view similarity reports and submission results but will not be able to upload submissions.

Similarity Threshold Email Notifications 

Administrators and Principal Users who own a shared folder can now configure automated email notifications that alert folder members when submissions in shared folders exceed specified similarity thresholds. Set custom thresholds for overall similarity scores and individual source matches at the parent-folder level.

This release will help you:

• Enhance collaborative workflows by automatically notifying all folder members when submissions require review, eliminating the need for manual checking across multiple shared folders
• Maintain rigorous review standards with customizable thresholds that can be configured differently across folders based on your specific requirements and workflows
• Streamline oversight and compliance processes through automated digest emails (daily, weekly, or monthly) that batch notifications for efficient communication

How can you get access to this feature?
This feature will be automatically available to all iThenticate 2.0 customers. No action is required to enable the functionality.

To configure similarity thresholds, Administrators and Principal Users can navigate to the details of any folder they own and access the Notifications tab. 

Note: The Notifications tab will only appear once the folder has been shared. From there, you can set your preferred thresholds for overall similarity and/or individual source matches, and configure your email notification schedule. 

All users with access to the folder will receive notifications when submissions exceed the configured thresholds.

AI writing detection data export

Administrators can now export AI writing detection data as a CSV file, providing organizations with greater flexibility in analysis. This feature allows administrators to export key metrics, enabling deeper insights into AI writing trends and usage within their organization.

This release will help you:

• Analyze AI detection and new standard assignment data at a more granular level.
• Identify trends and patterns in AI writing usage.
• Improve organizational understanding of AI writing's impact on research integrity.
• Facilitate custom reporting and analysis of AI writing data.

Administrators can access the new data export functionality through the Statistics section in the Administrator settings. The new "Export Data" option within the Statistics page will allow you to download the data in a flexible format for further analysis.

AI bypasser detection and other enhancements

We’re happy to announce that we’re expanding our AI writing detection capabilities to include AI bypasser detection. This enhancement will help educators identify likely AI-generated text even if it's been modified by an AI bypasser/humaniser, enabling them to uphold academic integrity in the face of this emerging challenge. These latest updates further ensure that Turnitin keeps pace with the evolving LLM landscape.

This expanded capability is available to all customers who have AI writing detection enabled on their accounts.

Why this matters:

• Deter potential AI misconduct: Our enhanced AI writing detection can now identify text that was altered by an AI bypasser to make it sound more human and evade detection. This capability helps deter students from using AI writing tools and potential misconduct.
• Draw actionable insights: Use the data and insights provided by our overall AI writing detection capabilities to start a formative discussion with students. The AI writing report highlights the text segments that our model predicts were likely written by an AI tool, including content that may have been further modified to avoid detection. Color-coded insights enable users to interpret results easily.
• Support your existing workflow: AI bypasser detection is part of our AI writing detection capabilities, which are built into our existing Similarity Report workflow. This means it’s already integrated with the learning management system you’re using. You can check student papers for text that is likely AI-written, including AI-bypassed content, as well as AI paraphrased content, without changing the way you work.

With this update, we can also detect content generated by GPT-5. While our model is not trained on GPT-5, our early internal tests on 100% AI-generated content from GPT-5, indicate that our AI writing detector is able to identify content generated by this LLM.

AI writing score visibility in the inbox

You can now view AI writing scores in the inbox view. This enhancement allows users to see AI detection results alongside other integrity results, such as the Similarity score, without needing to open individual Similarity Reports.

This release will help you:

• Save time and streamline workflows by viewing AI writing scores directly in the inbox, eliminating the need to open individual Similarity Reports.
• Prioritize reviews more effectively by quickly identifying submissions that may require closer review based on their AI writing scores.
• Gain valuable insights into AI writing usage patterns across entire classes by easily viewing and comparing AI writing scores at a glance, helping inform institutional policies.

How can you get access to this feature?

This feature is automatically available to all iThenticate 2.0 customers who currently license AI writing detection and have it enabled on their accounts
